A rare curative case of collecting duct carcinoma

Collecting duct carcinoma (CDC) is a rare form of renal carcinoma that has a poor prognosis. To date, there has been no report that the survival time of a patient with metastatic CDC could be more than six years. We present a case of rapidly advanced recurrence of CDC after nephrectomy that completely responded surgical intervention followed by targeted therapy with sorafenib and nivolumab.
